Hello! I have a iberital l'anna, and I would like to descale the boiler. My question is, how would it be best to do that? Every description I've come across talks about putting the descaler directly into a resovoir, and my machine doesn't have one of those. My current thoughts are to either:
1. fill a bucket with descaler and put the water intake hose in it, then allow the machine to fill up
2. pour the water in through the top by unscrewing the nut (?) on the end of the pipe that leads to the “hot water jet” (the hot water dispenser in the middle of the two group heads).
I'm leaning heavily toward the first method, does anyone have any advice? I would greatly appreciate it! I've linked a picture of the boiler with the part I'm considering unscrewing circled. -----> http://imgur.com/BqmRKA3
Thank you for any help!
